NAME

       Perlbal::Manual::FailOver - Fail Over mechanism in Perlbal

   VERSION
       Perlbal 1.78.

   DESCRIPTION
       How Perlbal's Fail Over mechanism works.

   Fail Over
       Whenever Perlbal fails to open a connection to a machine, it assumes that machine is not available and
       spreads the load between the remaining servers. It keeps trying to open connections to that server
       according to "error_retry_schedule".

       If there are no available servers, Perlbal will keep trying to open connections to the servers until
       "idle_timeout" is reached, upon which it will close the connection to the user. Clients interpret that
       closing differently: most will assume a 500 HTTP code, a few assume a 200 OK with empty content.

       For more information on parameters "idle_timeout" and "error_retry_schedule" see
       Perlbal::Manual::ReverseProxy.
